I just finished doing a "world" update and after rebooting wpa_supplicant would not connect to the wireless network. I remember having this same issue a few months back which turned out to be conflict between wpa_supplicant and libnl-3.2.2x, which I was able to solve by downgrading to "libnl-3.2.14". However, when I tried to do the same today, I got the following:

Thanks for the suggestion, I did boot into my system and after running "ifconfig -a", the name for my wireless adapter is the same as the one shown above "wlan0". Would you happen to know the command to search if "libnl-3.2.14" is still available in the repositories? Thanks._________________Gigabyte MA790X-UD4P Motherboard

and the following error came back "Could not insert 'ath5k': Unknown symbol in module, or unknown paramater". After digging around, I found out means that the modules trying to be loaded do not match the current kernel. I recompiled my kernel and after rebooting, all modules listed above loaded without any errors. However, wpa_supplicant is still not detecting my wireless adapter. All suggestions are welcome, thanks._________________Gigabyte MA790X-UD4P Motherboard
